Starting from this section, we will analyze the source code of each amps module. Chinese comments are added to the main sections. The tracing function is similar to the logging function used by software, but the recorded information is more detailed than the log. It can be used to see the running track of the entire code. amps supports the following trace levels: Error Warning Debug Debug_2 Info The

Look at the Log Module in amps. There are two ways to write logs. One is to write logs directly using encapsulated API functions, and the other is the log callback function registered at the application layer, use the event management mechanism to write. Amps_log.h #ifndef __HEADER_AMPS_LOG_H__#define __HEADER_AMPS_LOG_H__#include Amps_log.c # Include "amps_defines.h" # include "amps_linklist.h" # include "example" # include "amps_core.h" # includ

The cache mentioned here is not a high-speed cache in computer storage systems, but a software cache. It is mainly used to improve data processing efficiency. In amps, the cache structure is as follows: /* Cache structure */struct _ ampscache {void * pvhashtable;/* hash table for searching */void * pvheap;/* heap for adding, deleting, and modifying */intncachesize; /* cache size * // * Data Processing callback function */callback;};/* hash and heap n

The timer module is one of the key components of the Protocol server. Almost every protocol software has a timeout mechanism. In multi-threaded software, the biggest problem with the timer is to remove Asynchronization, which makes it inevitable to protect the data structure related to each session. APMs provides basic timer Management APIs. The main design objectives are as follows: The timer implementation must be efficient and there should be no searches or sorting in any operations relate

Efficient memory management is an essential feature of superior software products. If memory allocation and release involve costly search, sorting, and re-combination operations, memory Processing may become a bottleneck of system performance. The design objectives of the AMPs memory management subsystem are as follows: Memory Management must be fast and the system overhead is small. Minimize Memory leakage without introducing the garbag

The above section describes the memory pool implemented by using arrays + single-chain tables in amps. This section describes another implementation method. The idea of this method is as follows: its memory pool structure is a double-chain table that stores allocated memory information, a variable that represents the memory pool size, and a pointer linked list pointing to the current memory linked list node, as follows: /* Memory Pool Structure */str

MD5 is a hash algorithm used to ensure the integrity and consistency of information transmission. The algorithm IDEA is as follows (from Wikipedia ): MD5 is an algorithm that outputs a fixed length of 128-bits. After the program flow, four 32-bit data are generated, and finally merged into a 128-bits hash. The basic method is to calculate the remainder, take the remainder, adjust the length, and perform cyclic operations with the link variable. Result. YesXOR,And,Or,Not. An MD5 operat

power on the line, the battery is small and the UPS host in the same box, so that most people are not aware of the existence of the battery. To a 2000 square meters of Securities sales Department of all IT equipment to provide power security services to the UPS to have 200KVA (200,000 KVA, volts, amps, are high school physics units. Specific this number do not remember, just temporarily to check a few year

differential mode input voltage. NE5532 DC indicators are as follows: Input offset voltage Vos:The input offset voltage is defined as the compensation voltage added between the two inputs when the output voltage of the integrated op-amp is zero. The input offset voltage actually reflects the circuit symmetry inside the Op Amplifier. The better the symmetry, the smaller the input offset voltage. Input offset voltage is a very important indicator of an operational amplifier, especially when a

The user shall select the required UPS Output Power KVA value based on the statistical value of the device load). To ensure the UPS system efficiency and prolong the UPS Service life as much as possible, the recommended parameters are: the user load only accounts for 60% of the UPS output power ~ 70% is recommended.
